Glue dripping from ridge vent

[jimy]

Last year a new metal roof was out on my pole barn. They put the “scotch Brite like” stuffing between the roof and ridge vent to keep the critters out and let it breathe. We thought the car we keep there was getting pine sap somewhere else. It looks to me that some adhesive from the stuffing is dripping down on hot days.

Has anyone had this problem?

I'd bet it's sap coming out of the wood. Is it the right color (honey). The "scrubby pad" filter usually comes in a 50' roll and just laid across the ridge until the cap and screws are installed. I've never seen one glued down to the roof or instructions to do so.

Those are vented closures with stickem on them so they stay in place while the ridge cap is installed. It looks like the sheets are to short because you shouldn’t be able to see the closures.
Back to the point. I have had those things riding around in the truck in the summer and never have seen the adhesive drip off. I think there are some pitch pockets in the wood. They may be on the side or even the top making them hard to see.

Thanks for the ideas. I don't believe it can be pitch. It is only dropping stuff directly below the closures. The trusses are 10+ years old so I don't know how much pitch could be there at this point.

I got smart and remembered I had a short section of extra closure. The unused section has more of a line of glue than the droplets I see on the installed closure. These droplets are fairly consistent across the 24' of closure.

The only somewhat simple way to block this might be to cut long plywood strips to screw to the purlins next to the ridge cap (between trusses). But then, the heat would only get out between the purlins and the grooves in the metal roof. Would that tend to hold heat in?

Jim, you're missing an opportunity to explain to the mrs. that you need air conditioning to stop this.
